Alpha-particle beta-particle gamma ray proton neutron The half-life of bromine-74 is 25 min. How much of a 4.0 mg sample is still active after 75 min? 2.0 mg 1.0 mg 0.50 mg 0.25 mg 4.0 mg One way to enhance your learning in chemistry as well as other STEM classes is to study a little every day equation? form a study group go to office hours be an active learner all the above

Explanation / Answer

Q.No-27 (a)

Alpha emission is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into an atom with a mass number that is reduced by four and an atomic number that is reduced by two.

Q.No -28 (b)

This is an example of Beta particle. In the given nuclear reaction mass is same but atomic number is increased by 1

Q.No -30 (E)

All the given choices are correct to enhance your learning in chemistry as well as other STEM classes.
